So far it is believed that, for every series-parallel planetary gear system (PGS), as a coupled gear, a very harmful phenomenon of power circulation must occur in at least one of its closed circuits. In this paper (Part I) and in the next two (Part I

Versatile hypotheses of fatigue damage accumulation are utilized in order to determine the fatigue life of particular mechanical elements. Such an approach to an analysis of fatigue processes is recognized as being phenomenological. In the present pa

We consider aggregations of fuzzy relations using aggregation functions of $n$ variables. After recalling fundamental properties of fuzzy relations we examine aggregation functions which preserve reflexivity, symmetry, connectedness and transitivity
